2008 C300. Tried the battery display on the menu today: Smart Key inserted; Accessories on; Press "Answer Phone" first then "OK'. Brings up "Service/Back" menu. Go to "Vehicle Data" and scroll to "Battery". My display showed 12.2V/-15.1A. Seems very high current draw with only the display operating. No fans or anything else operating. Anyone get a reading like this usinf the battery display feature?
